Industrial lithium cells lack built-in protection circuits (PCMs/BMS). Operating outside designated limits poses severe safety risks. Operational Range Critical Limit / Risk 0°C to 45°C
The following table summarizes the complete datasheet specifications for the Panasonic NCR21700T lithium-ion battery cell:
The chemistry of the NCR21700T allows it to maintain its capacity over many cycles, often cited for over 1000 cycles under appropriate charging/discharging conditions, making it a cost-effective choice for long-term investments. 3. Discharging Characteristics (Voltage Curve)
Lithium-ion chemistry is highly sensitive to ambient and operational temperatures. Operating outside these datasheet boundaries can cause thermal runaway or permanent capacity loss. 0°C to 45°C Discharge Temperature Range: -20°C to 60°C
